Ok, so I just installed by HBI trigger, and I'm having a slight issue. If I pull the trigger back very slowly, it sometimes doesn't want to release the striker. It's like it hits the "wall" at the back of the trigger, but you have to push harder against the "wall" to get the striker to release. Not sure if my explanation makes sense, but it doesn't do this all the time, just SOMETIMES when i press the trigger VERY slowly. It's like it's hanging up on something, but Idk what it could be. Any help would be greatly appreciated!

Are you using the 3.5lb striker spring by chance? I just installed a HB trigger in my P10c and get the exact same thing happening, but only with the 3.5lb Spring. The factory one and the 3lb HB spring don't do this. Maybe it has something to do with it being longer, perhaps it is rubbing something just enough somewhere. Hopefully someone with a bit more knowledge can shed some light.
I didn't change any springs. Just the shoe.

The trigger on my FDE P-10 started doing this lately even after I swapped back in the factory trigger. It's not the trigger but a combination of the trigger bar and the striker sleeve. Compared to my black trigger bar, the "hook" that catches the striker leg sticks up about 1/8" higher when fully back. Normally, it's still low enough to release the striker except when the slide and slide plate are pushed down. The striker liner is flexible enough to allow the whole assembly to squeeze slightly out of the slide's striker channel. The resulting lowering of the striker leg, means the trigger bar can't move down far enough to cleanly release it. If I push the cover plate up, it raises the striker enough to release from the trigger bar. I swapped, strikers, trigger bars, connectors, and the rear housings around, but the only thing that made a difference was the trigger bar. Examining the two, the lug on the FDE is cut lower, resulting in a higher "hook". Not sure of a solution yet, short of filing down the shelf or striker leg. I'm going to post pics/video this evening when I got home from work.
I'm looking forward to your video. I've got a black P10, put the 3lb striker spring back in and this issue has gone away. If I pull the trigger exceedingly slow it will sort of do this, but any regular trigger pull seems fine for now.
At first I thought the 3.5 spring was too long and getting fully compressed, stopping the trigger from moving fully rearward. But it only has 2 more active coils than the 3.0, so I don' t think that's the case. Maybe the extra friction from the slightly heavier spring, is letting the striker leg get dragged further down. With striker fired guns, I've always noticed more consistent trigger pulls with a mag full of dummy rounds. The rounds provide more magazine spring pressure to force the slide to its highest position on the rails, while with no dummy ammo/mag, the slide is pretty much free to rest at any height. The P-10C has a pretty sloppy slide to rail fit for reliability (normal for striker fired guns) and the cover plate has some movement which exacerbates the inconsistency. When fitting Ghost connectors with over-travel tabs for my Glocks, I always push the slide down while dry firing to ensure the trigger bar will always release the striker.
The biggest issue is the striker housing. Since its plastic and open at the rear, the slot can get squeezed if you press the slide cover down, and the spring pressure can hold it there. I think it's the reason for one FTRTBs I had when the plate dropped enough to hang on the rear of the trigger housing, preventing the last 1/8" of slide travel. Some newer P-10C have a bevel on the slide plate to let it ride back up if it gets too low. Fortunately, when in battery, the slide plate does limit the amount the striker assembly can drop down. Short of sending my P-10C back to CZ (I've modified mine enough that I probably voided the warranty) I think the immediate solution is to bevel the bottom front edges of the slide cover plate, and shave 0.010" off the trigger bar on the mill. I have a feeling I'll be overhauling some of my parts once spares become available.
